Mint, complete 2-card promotional set for the 1997 Upper Deck MLS product. The two players are Carlos Valderrama and Alexi Lalas. These cards are similar in design to the regular 1997 MLS cards, but have no card number on the reverse. Interestingly, the Lalas card has Alexi on the correct team (New England Revolution) and has his correct stats. The Lalas card in the regular MLS set mistakenly has the stats of Colorado Rapids player Marcelo Balboa. Thus, the promo card is the only way to get Lalas' correct team and stats.
